the 25tli March, 1875, liave recently come under my notice, 
and have been identified by our best authority on the Ster- 
ninse, Mr. Howard Saunders. This Tern has, I believe, been 
only known to inhabit the Red Sea; and as it forms an ad¬ 
dition to the fauna of India, its occurrence on the western 
shores of that country may not be unworthy of record in 
your pages.

Sir, —I have just received from Dr. Briiggemama copy 
of his paper “ Beitrage zur Ornithologie von Celebes und 
Sanghir/'’ printed in the ' Abhandlungen herausgegeben vom 
naturwissenschaftlichen Verein zu Bremen/ Band v. S. 35- 
102, Taf. iii., iv. (1876). I wish to make a few remarks on 
some points already noticed in a paper which I have pub¬ 
lished in the f Annali del Museo Civico di Storia Naturale di 
Genova/ vol. vii. p. 641-681, tav. xviii. (1875), with the title 
“ Intorno a due collezioni di Uccelli di Celebes, inviate al 
Museo Civico di Genova dal Dr. O. Beccari e dal Signor A. 
A. Bruijn.” Dr. Briiggeman, seems not to be acquainted VIj 
with my paper. 
Page 51, Halcyon cyanocephala. The author confirms the 
idea expressed by me that this species is really different from 
Monachalcyon princeps. 
Page 80, sp. 99, Ptilinopus melanocephalus , var. celebensis, 
Briigg., is my lotreron melanospila (Ann. Mus. Civ. Gen. vii. 
P- 671). 
Page 80, sp. 100, Ptilinopus nuchalis, Briigg., seems to be 
my I. xanthorrhoa (/. c.) . 
Page 81, Ptilinopus sulaensis, Briigg., is my I. chrysorrhoa 
(/•<••). 
Page 88, Megacephalon maleo. I have shown (/. c. p. 673) 
that this bird was first described by S. Muller. 
Page 94. The genus Schizoptila , Briigg., has the same 
type as my genus Gyrnnocrex (l. c. p. 678).
